Question about Reliance 43614 Heater

Water Heater Burner Won't Stay Lit

Reliance Sta-Kleen 805 Power Vent Natural Gas Water Heater
Burner will not stay lit, goes out in 4-5 seconds. Cycles through three times then locks out.

From the troubleshooting guidelines: outlet polarity is not reversed, ambient room temp is not too high, air intake screen is clean, flame arrestor opening is not blocked. Maybe a defective gas valve?

I had problems with the vent pipe in the attic melted and blocked the exhaust. Fixed.

I also replaced the hot surface ignitor.

It still sporadically locks out. Sometimes all day, sometimes just for one cycle.

Should I replace the gas valve? $262!

    Pay no attention to the title of the post. It is not a Reliance 43614. It's a Reliance Sta-Kleen 805 power vent natural gas...40 or 50 gallon

My water heater pilot light won't stay lit


I would try cleaning the thermo couple surfaces with some steel wool... Both where the flame contacts the sensor, and the electrical contacts. Even a small increase in voltage may be enough to hold the pilot valve open. Both black, and white soot on the sensor end, can act as an temperature insulator, lowering the output voltage.
As for finding the part numbers for replacement: http://www.reliancewaterheaters.com/media/48391/242117_RPPCR01111-Reliance-Parts-Catalog.pdf

Pilot light not stay lit

Reliance is made by AO Smith company, and air intake located on bottom of unit.
Make sure you have adequate incoming air and vent is working.
Remember, the pilot is located upwards from the viewing sight-glass, so it is sometimes difficult to see pilot.
Pilot flame must burn clear blue, with bits of yellow and red. Yellow flame means inadequate air supply or venting.

Replace thermocouple gas water heater


Thank you for the brand. Approx how old is water heater? 2nd and 3rd digit of serial number are year of manufacture.
For general instructions:
http://waterheatertimer.org/How-to-replace-thermocouple.html

Reliance is AO Smith, and air intake is located on bottom of tank.
Inspect and Clean intake.
Do NOT underestimate need to keep air intake clean because the arrestor screen is fine mesh and once clogged will cause heater to fail. Older models might need full replacement and at least parts.

Product manual?
These gas water heaters are changing quickly today. The Reliance site shows the 909 but not 805
http://www.reliancewaterheaters.com/lit/om.html
The older designs are different, but instructions shown above will help.

Reliant 501 Natural Gas won't stay lit


Reliance water heater?
Thermocouple is good if the pilot stays lit continuously.

501 is older model. Unknown if this unit has FVIR protection and sealed combustion chamber or open air intake on front of unit.
http://waterheatertimer.org/pdf/Reliance-2006-Service-Handbook.pdf

With FVIR protection:
Get more fresh air to the unit.
Clean the flame arrestor screen.
Test and replace the thermocouple:
http://waterheatertimer.org/How-to-test-water-heater-thermocouple.html
Inspect and clean burner and combustion parts
Test gas pressure, bleed air out of gas line.
Replace gas control valve.
Test draft air by lighting match and see if smoke is pulled into the vent pipe at draft hood on top of tank.

The pilot won't stay lit on gas hot water tank.


Make sure thermocouple tip is seated inside the burner flame.
Make sure thermocouple is not overtightened. Finger-tight + 1/4 turn.
If the pilot lights, then ECO energy cut off is not tripped, but gas control valve might be bad.
Check color of pilot flame: it should be strong and clear blue.
If pilot flame is weak, or color of flame is yellow-orange: Clean pilot orifice and burner and combustion parts on yearly basis.
Clean air intake screen if applicable.
Increase air supply to water heater. Open a window and see what happens.
Check for adequate draft going up chimney using match under vent hood to see if smoke drafts immediately upwards.
Bleed air out of gas line.
Check gas pressure.

Reliance 606 natural gas water heater - model #640YORT - water does not stay hot. pilot has to be clicked to heat and then u can use hot water til tank empty and it will not continue to heat water.


If I understand correctly, the pilot light is not staying lit.
You light the pilot and water in the tank reaches temperature.
Once hot water is gone, then pilot light has to be lit again.

Gas pressure is good, and gas is flowing.
Thermostat is working at high end because it cuts off heating.
Vent is working because tank heats up.
Air intake is working.

Gas control thermostat might not be reading low temperature. Replace gas control valve.
Pilot tube might be dirty. Clean burner parts and combustion chamber, and air intake, and vent.
Backdraft might be blowing out pilot. Check for constant updraft by running water heater 5 minutes, and then light match under vent hood and see if smoke goes up.
Very hot air can put out pilot, especially when water heater located in attic. Add ventilation.
Improper vent might have water dripping back down into combustion chamber and putting out pilot light and rusting out the parts. Inspect for rusted parts and water.

Most gas water heater problems can be solved by having service technician perform yearly maintenance. Or by doing maintenance yourself.
This maintenance includes cleaning burner parts and combustion chamber, checking gas pressure and supply, bleeding air out of gas line, checking vent draft, making sure air supply is adequate and not exposed to chemicals, cleaning air intake. Also adjusting flame sensor so it is positioned correctly. If water heater is connected to electric circuit, the outlet must have correct polarity.

You can get gas to appliance indicates the gas control valve and water heater are not locked out. But the gas control valve thermostat can still be bad.
